Case Name   : 【事件触发器】REFRESH MATERIALIZED VIEW命令触发事件触发器
Create At   :2024/07/08
Owner       :sungang14
Description :
    预置条件：
        1.创建事件触发器：
        CREATE OR REPLACE FUNCTION f_eventtrigger_0003()
        RETURNS event_trigger
        LANGUAGE plpgsql
        AS $$ BEGIN
        RAISE NOTICE 'test_event_trigger: % %', tg_event, tg_tag;
        END;
        $$;
        
        CREATE EVENT TRIGGER start_eventtri ON ddl_command_start EXECUTE PROCEDURE f_eventtrigger_0003();
        CREATE EVENT TRIGGER end_eventtri ON ddl_command_end EXECUTE PROCEDURE f_eventtrigger_0003();
        CREATE EVENT TRIGGER drop_eventtri ON sql_drop EXECUTE PROCEDURE f_eventtrigger_0003();
        CREATE EVENT TRIGGER rewrite_eventtri ON  table_rewrite EXECUTE PROCEDURE f_eventtrigger_0003(); 
         
         2.创建物化视图
         create table t_eventtrigger_0003(
         t_eventtrigger_0003_no int4 primary key, 
         t_eventtrigger_0003_name varchar(30), 
         age int2 ); 
         insert into t_eventtrigger_0003 values(1,'xiaoming',12); 
         insert into t_eventtrigger_0003 values(2,'xiaohong',11); 
         create materialized view mv_eventtrigger_0003 as select * from t_eventtrigger_0003;
         
    测试步骤：
        1、REFRESH MATERIALIZED VIEW mv_eventtrigger_0003;
Expect      : 
    1、触发执行函数f_eventtrigger_0003()
